Yes.
Put a multimeter on the 10A current setting. The put direct across one panel.
The current you read will be the I Max.
...
Or connect the panel leads together and use a clamp meter to get the Amp readings.

You're right that you will not get 6 days out of the battery with the fridge running. I can't see the wattage of that panel you show in the picture. I have a 100w renogy folding panel like that that is ok for keeping the leisure battery topped up but really needs a good sunny day to do so well.
Just a quick one after a search on here . Looking at installing a Victron smart mppt in my van .
Current system is 100W panel with 100Ah AGM
Want a more efficient user friendly mppt so looking at Victron Smart BT should I buy 75/10 or 75/15 ?.
Any advice people?
These panels x 2.
This lifepo4 battery.
Heating is pretty much the main reason I have setup the electrics. I suddenly realized that when it is required most, to power the heater components is when the solar will be least effective.
So is it hopeless or can you draw enough to power heating...
...efficiency. I'd have thought it to be proportionate as in 10% shade = 10% loss but his testing suggests that 10% shading is more likely to result in 50-75% loss. When he places the chair on the Renology panel covering about 40% of the panel it was only harvesting 1.5w out of a possible 100w...
100W in Summer is fine provided the sun comes out. Of course a bigger panel gives you more margin but there’s always a trade off on size, weight etc.. etc… especially with portable panels. I’ve just purchased one of the following to play with, but haven’t managed to even get it out yet with the...
...significant power, it's 2 network devices and low range radio (and the one in your phone runs for a day off battery) so I'd anticipate around 100w - a bright lightbulb in old money -but it's reasonable to ask Vodafone how much it does use.
100w would be 2.4 kWh a day or 876 a year, so that...
...You'll then have the option of upgrading to a 200w portable panel or 200w roof panel and use the same controller. You'll also get closer to the 100w from your portable panel rather than the 60-70w max you'll get with the PWM controller
Your CRX50 fridge will be using 1-1.5Ah per hour, and...
...inverter efficiency is 85%. Therefore you lose 15%.
So, the 700W heater will draw approx 805W.
Running for 25% time call it 200W per hour.
100W of that will come from the 2 additional batteries.
That means the delta2 will be flat in about 8 hours.
It doesnt matter how big your additional...
Just spotted that the older 100w Renogy folding panels were at a low price on Amazon (£87) and also I was offered a voucher bring them down to £65.
Not sure if that voucher would be offered to everyone but at £65 delivered I figured it was worth a shot to play with as both my power packs and...
Hi,
Just got an Ecoflow River and looking at portable/folding solar panels that will fit comfortably on the dash that are 100w or more.
Won't need to be there whilst driving but just parked up so can overhang to steering wheel.
Done a bit of whittling down and it is probably between Ecoworthy...
Just the cheap renogy 100w. They on eBay for £79 delivered
I got the charge cable from eBay too £22

That’s what I was thinking … the £425 is just the labour cost for fitting the warranty replacement using the existing MPPT. The higher cost would include the value of the larger solar panel. Seems a lot extra when the cost off the panels is compared. The wiring and MPPT would be essentially...
Hi All,

...panel to avoid the hell of adhesive removal off the roof. Will see how it goes staying put . Then wire it up tomorrow via mc4 connectors this time and new cable with split mc4 so I can plug in an additional 100w Solar panel if needed to boost things up a bit in hotter weather whilst out n about.
